I've seen a lot of posts of people having problems using Distinct() and/or Sort() with custom objects.
Here is an example showing an implementation of both (in C++, C# and VB).
This post includes custom Compare methods, the implementation of Distinct() and the use of List.ForEach in the 3 main dot net languages.

I have seen a few examples of VBS scripts used to get the User ID, Domain and SID of the current user.
This information is valuable when making registry modifications for the current user programatically.
I needed a way to retrieve that information in a .NET module to include in other .NET programs.

This (console app) example calls to two different web services. One of which returns raw XML as the result and the other returns a regular (pre-parsed) object.
This can be used as a reference for XML and SOAP and a minor LINQ reference.
